Circuit voltage above threshold Carry out any pinpoint tests associated with this DTC
using the manufacturer approved diagnostic system Pinpoint Tests

PINPOINT TEST A : FRONT SEAT FORE/AFT MOVEMENT NOT FUNCTIONING TEST
CONDITIONS DETAILS/RESULTS/ACTIONS A1: CHECK FOR FRONT SEAT FORWARD-REARWARD SEAT MOTOR OPERATION
WARNING: Before work is carried out, make the air bag supplemental restraint system safe. For
additional information, refer to Standard Workshop Practices section of workshop manual. 1 Set ignition status to ' ON'. 2 From the switch pack, operate the front seat forward-rearward seat motor switch and listen for evidence of the motor operating. Does the motor operate? Yes
GO to A2. No
GO to A3. A2: CHECK FRONT SEAT FORWARD-REARWARD SEAT MOTOR DRIVE BAR 1 Check front seat drive bar for correct installation and condition Is the front seat drive bar correctly installed and in a serviceable condition? Yes
Re-check for correct front seat forward-rearward movement. Remove seat to allow for further investigation
if required.
No
Correctly install front seat forward-rearward seat motor drive bar, or replace if required. A3: CHECK FRONT SEAT FORWARD-REARWARD SEAT MOTOR
WARNING: When carrying out the following steps, stand clear of all moving parts and ensure link harness is routed
accordingly. 1 Set ignition status to 'OFF'. 2 Disconnect front seat forward-rearward seat motor connector.

NOTE: It may be that the seat has been driven to the limit of travel along the relevant axis, and when
the link harness is connected, the seat will remain in the same position. If this is the case, a jolt may be felt
from the motor. To confirm the motor operation, swap the link harness to alternate motor pin connections and
the seat should travel in the opposite direction. 3 Using a locally made fused link harness and power supply, connect power and ground to forward-rearward seat motor. Battery positive terminal Battery negative terminal forward-rearward seat motor pin 1 forward-rearward seat motor pin 2 Does the motor operate? Yes
Using manufacturer approved diagnostic system, check for related Diagnostic Trouble Codes (DTCs) and
carry out the repair operations specified. Alternatively, refer to the electrical circuit diagrams and check
front seat forward-rearward seat motor circuits.
No
Replace front seat forward-rearward seat motor. Refer to relevant section of workshop manual.
PINPOINT TEST B : FRONT SEAT EXCESSIVE FORWARD-REARWARD FREE PLAY TEST
CONDITIONS DETAILS/RESULTS/ACTIONS B1: CHECK FRONT SEAT FOR EXCESSIVE FORWARD-REARWARD FREE PLAY
WARNING: Before work is carried out, make the air bag supplemental restraint system safe. For
additional information, refer to Standard Workshop Practices section of workshop manual. 1 Check all accessible front seat frame fixings are installed and to the correct torque. Are all accessible front seat frame fixings installed and to the correct torque?
Yes
GO to B2. No
Install and tighten all accessible front seat frame fixings to correct torque and re-check for excessive
free play. www.JagDocs.com
